Abstract

In this work a computer model for calculating surge distribution in transformer windings is presented. The transformer model is developed using transmission line theory. The capacitance, inductance, resistance and conductance are calculated with simple formulations. The electrical parameters are used for calculating modal parameters in order to represent the winding as a two port network. The model is validated by means of a comparison between measured and calculated voltages in a power transformer disk with 16 turns.
